Abstract: The rail anchor system includes two pins and two clips. Each pin extends through a horizontal transverse bore in a cross-tie. The pins have extensions at each end exposed on both sides of the cross-tie and the bores are parallel to and substantially within the outer edges of the bottom flange of the rail which sits on the cross-tie. Two resilient clips form a part of the system. Each clip has a looped section, a hooked extension extending from one end of the looped section and a lever extension extending from the other end of the loop section. A clip is used on each side of the tie with the loop sections engaging the pin extensions of opposite pins and the lever extensions being locked by opposite pins when the respective hooks are in engagement with the cross-tie.
Abstract translation: 轨道锚固系统包括两个销和两个夹子。 每个销延伸穿过交叉连接的水平横向孔。 销在每个端部处具有在横梁的两侧上露出的延伸部分，并且孔平行于并且基本上位于位于十字架上的轨道的底部凸缘的外边缘内。 两个弹性夹构成系统的一部分。 每个夹子具有环形部分，从环形部分的一端延伸的钩状延伸部和从环形部分的另一端延伸的杆延伸部。 在连接件的每一侧使用夹子，其中环部分接合相对销的销延伸部分，并且当相应的钩与交叉连接件接合时，杠杆延伸部被相对的销锁定。
